SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill removes the manual effort of authoring and maintaining structured Low-Level Design documents for backend and infrastructure work, keeping component-level architecture consistent and traceable.

Core Features & Use Cases

  • Drafting and merging LLDs: Creates new component-scoped LLDs or edits existing drafts without overwriting untouched sections.
  • Template-driven structure: Selects the correct backend or infra template and preserves the required 14-section canonical order with explicit anchors.
  • Operational safeguards: Uses atomic writes, Mermaid validation, provenance stamping, and changelog updates to keep documents reliable and auditable.

Quick Start

Ask the lld-docs skill to generate or update the LLD for the target component using the available PRD, TRD, and repository evidence.

FAQPage Schema
How do I generate a low-level design document for a backend component from a PRD?▼

To generate a low-level design document, provide a PRD, TRD, or repository evidence to automatically draft a component-scoped LLD using a 14-section canonical structure with backend or infra template selection.

What is the canonical structure for a low-level design document?▼

The canonical structure for a low-level design document requires 14 specific sections with explicit anchors, ensuring component-level architecture remains consistent, traceable, and properly ordered for backend and infrastructure work.

How do I update an existing LLD draft without overwriting untouched sections?▼

To update an existing LLD draft without overwriting untouched sections, the tool merges canonical and draft LLDs under docs/lld and docs/shield feature paths while preserving the original 14-section structure and provenance.

Does the LLD generation process validate Mermaid diagrams and track changes?▼

Yes, LLD generation validates Mermaid diagrams and tracks changes through automated changelog updates, applying atomic writes and provenance stamping to keep infrastructure design documents reliable and auditable.

Can I use repository evidence to draft infrastructure design documents?▼

Yes, you can use repository evidence alongside PRDs and TRDs to draft infrastructure design documents, automatically selecting the correct infra template and applying the required 14-section canonical order with explicit anchors.
